This is unique to Matthew among the gospel writers, although in the Acts of the Apostles, chapter 1:16-20, Peter talked about the death of Judas and the Field of Blood. The chief priests, however, took the 30 pieces of silver (οἱ δὲ ἀρχιερεῖς λαβόντες τὰ ἀργύρια). They said that it was not lawful to put this money into the Temple treasury (εἶπαν Οὐκ ἔξεστιν βαλεῖν αὐτὰ εἰς τὸν κορβανᾶν), since it was blood money (ἐπεὶ τιμὴ αἵματός ἐστιν). After conferring together or taking counsel among themselves (συμβούλιον δὲ λαβόντες), they used this money to buy the potter’s field (ἐξ αὐτῶν τὸν ἀγρὸν τοῦ κεραμέως), as a place to bury foreigners or strangers (εἰς ταφὴν τοῖς ξένοις). Thus, this field has been called the Field of Blood (διὸ ἐκλήθη ὁ ἀγρὸς ἐκεῖνος Ἀγρὸς αἵματος) to this day (ἕως τῆς σήμερον). Apparently, the clay that was used for pottery was useless for growing anything. Thus, it was called potter’s field. This field became a graveyard for foreigners, strangers, and commoners who had no money for a proper burial. It was the poor man’s burial area. This returned blood money could not be used for any Temple activities or holy purposes. Thus, a cemetery for the indigent seemed like a good comprise. Notice that Matthew said that it was called a “Field of Blood” even until the time of his writing, this day, indicating an interval between this incident and the writing about it
